An attic truss fixes the main issue with standard roof trusses—the lack of habitable space. The internal webs that support your roof with a standard fink truss also prevent the attic from being made into a room, however, an attic truss removes the internal webs and uses greater timber sizes elsewhere to provide you with a habitable room. This extra room in your attic can become a bedroom, office, bathroom, office or just a storage space, and vastly increases your home's overall floor space. As well as this, they can increase property values and reduce heat loss through the roof, making them a valuable choice for any homeowner. Attic trusses cost more upfront but will pay themselves back in the long run. All trusses are made from structural grade TR26 timber and as standard are not treated.
